The Alaska Peninsula is a peninsula extending about 800 km (500 miles) to the southwest from the mainland of Alaska and ending in the Aleutian Islands. A peninsula is a piece of land that is nearly surrounded by Water but connected to Mainland via an Isthmus. Alaska ( Аляска Alyaska) is a state in the United States of America, in the northwest of the North American continent The Aleutian Islands (possibly from Chukchi aliat, " Island " are a chain of more than 300 small volcanic islands forming a Volcanic The peninsula separates the Pacific Ocean from Bristol Bay, an arm of the Bering Sea. The Pacific Ocean is the largest of the Earth 's Oceanic divisions Bristol Bay ( Iilgayaq in Central Yup'ik) is the eastern-most arm of the Bering Sea, at 57° to 59° North 157° to 162° West The Bering (or Imarpik) Sea is a body of water in the Pacific Ocean that comprises a deep water basin (the Aleutian Basin) which rises through

Geography
The Aleutians are a highly active volcanic mountain range which runs along its entire length. The Aleutian Range is a major Mountain range of southwest Alaska, extending from Chakachamna Lake (80 miles/130 km southwest of Anchorage to Unimak Plate tectonics and hotspots Divergent plate boundaries At the A mountain range is a chain of Mountains bordered by highlands or separated from other mountains by passes or valleys It contains several U. S. National Parks and Wildlife Refuges, including the Katmai National Park and Preserve, the Aniakchak National Monument and Preserve and the Becharof National Wildlife Refuge, the Alaska Peninsula National Wildlife Refuge, and Izembek National Wildlife Refuge. Katmai National Park and Preserve is a United States National Park in southern Alaska, notable for the Valley of Ten Thousand Smokes and for its Brown Aniakchak National Monument and Preserve is a US National Monument and National Preserve, consisting of the region around the Aniakchak Volcano The Alaska Peninsula National Wildlife Refuge is a United States National Wildlife Refuge in southwestern Alaska whose use is regulated as an ecological-protection The Izembek National Wildlife Refuge is the smallest of the National Wildlife Refuges located in the U
The southern-most side of the Alaska Peninsula is rugged and mountainous, created by the uplifting tectonic activity of the North Pacific Plate subsiding under a western section of the North American Plate; whereas the northern side is generally flat and marshy, a result of millennia of erosion and general seismic stability. The Pacific Plate is an oceanic Tectonic plate beneath the Pacific Ocean. The North American Plate is a Tectonic plate covering most of North America, Greenland and part of Siberia. Erosion is the carrying away or displacement of solids ( Sediment, Soil, rock and other particles usually by the agents of currents such as wind Seismology (from Greek grc σεισμός seismos, "earthquake" and grc -λογία -logia) is the scientific study of Earthquakes
The differences between the northern and southern shores of the Alaska Peninsula are a study in contrasts. While the northern Bristol Bay coastal side is generally turbid and muddy, experiences tidal extremes, and is relatively shallow, the Pacific side has relatively small tidal activity and is very deep and clear. Bristol Bay ( Iilgayaq in Central Yup'ik) is the eastern-most arm of the Bering Sea, at 57° to 59° North 157° to 162° West The Pacific Ocean is the largest of the Earth 's Oceanic divisions
Climate
In the south coast of the peninsula temperatures fluctuate between 0 ºC to -2. 0 ºC (28 ºF - 32 ºf) in winter and 11º C (52 ºF) in Summer. Rainfalls are fairly steady. The climate of the south coast is only comparable to those of: Aleutian Islands, Iceland, and Tierra del Fuego
Flora and Fauna
The peninsula is devoid of trees. The Aleutian Islands (possibly from Chukchi aliat, " Island " are a chain of more than 300 small volcanic islands forming a Volcanic Iceland, officially the Republic of Iceland ( ( Ísland or Lýðveldið Ísland ( Tierra del Fuego ( Spanish for " Land of Fire " in English tiˈɛərə dɛl ˈfweɪgoʊ] Spanish ˈtjerað̞elˈfweɰo is an Archipelago The Alaska Peninsula and Bristol Bay are home to the world's largest sockeye salmon runs in large part because the Alaska Peninsula is host to so many large lakes, which are an important element in the lifecycle of Oncorhynchus nerka, sockeye salmon. Bristol Bay ( Iilgayaq in Central Yup'ik) is the eastern-most arm of the Bering Sea, at 57° to 59° North 157° to 162° West Sockeye salmon ( Oncorhynchus nerka) also called red salmon or blueback salmon, is an Anadromous Species of Salmon These salmon, after returning from their short life at sea, swim into the lakes and their contributing streams to spawn. Their offspring, or fry, overwinter in the deep and food-abundant depths of these lakes until their migration to the sea in one or two years.
The Alaska Peninsula is also home to some of the largest populations of native and undisturbed wildlife in the United States. Besides the famous McNeil River and Katmai brown bear populations, large herds of caribou, moose, wolves and waterfowl inhabit the area. The McNeil River is a river on the eastern drainage of the Alaska Peninsula near its base and conjunction with the Alaska mainland at 59°073'N Latitude / 154°14' The Brown Bear ( Ursus arctos) is an Omnivorous Mammal of the family Ursidae, distributed across much of northern Eurasia and The moose (North America or elk (Europe Alces alces, is the largest extant Species in the Deer family. The grey wolf or gray wolf ( Canis lupus) also known as the timber wolf or simply wolf, is a Mammal of the order Carnivora

Lake and Peninsula Borough is a borough located in the state of Alaska, United States.
